You will have to have the cases bored to fit the big bore and on some cases need clearance machined. That's not normal but has happened. If you buy the SS kit then you have all you need. I'm looking at the axtell mountain motor. A little less money and you still have the same rpm capability, plus no change in engine heigth. I have to put a new crank in the motor on the donor bike, so while it's apart might as well bore the cases, and the 88 kit is the same as a 1250. I'll go all cat iron, and build it as I go. No hurry since I have a nice sport motor in great shape.
